Implement namespace-owned stream rendezvous with incarnation isolation, cancellation, recovery, bounded local byte rings, and host/child actor protocols. Add a replaceable stream transport boundary plus an Iroh ALPN adapter with framed records, backpressure, reconnect handling, and terminal propagation. Wire stream sources and sinks through Myelin job deployment and Python bindings, with guarantee coverage across blob, namespace, job, byte-ring, and transport paths. Sanitize nested Cargo build context in xtask so lint, Nextest, doctest, and maturin invocations retain stable fingerprints. |

iroh-driver
iroh-driver is the iroh-backed transport bridge for the actorized distribution stack. It owns the concrete iroh endpoint, QUIC connections, relay configuration, peer authorization, and frame shuttling between iroh and swactor actor mailboxes.
Engine ownership
The driver runs on a caller-supplied swactor EngineHandle — the
single engine that owns the node's Tokio substrate. All accepts, reads, dials,
writes, retries, and teardown are scheduled through that handle; the driver
stores no raw Tokio handle and performs no ambient-runtime detection
(ENGINE_SPEC.md §7).
let driver = IrohDriver::with_engine(engine.handle(), config)?;
The driver validates that the engine provides the tasks, timers, and io
capabilities before binding the endpoint or starting any background work
(ENGINE_SPEC.md). Endpoint construction runs as an engine-hosted
task; with_engine blocks on a synchronous channel until the endpoint is bound
(or fails), so callers need not enter or possess the raw substrate runtime.
Engine-hosted progression
All adapter progression — actor-bridge ingress/egress, telemetry ingress, and
edge ingress — is driven by an engine-hosted interval pump installed via
install_actor_bridge_pump. Applications do not (and cannot) manually pump
these adapters; the single engine owns progression for the node's lifetime
(ENGINE_SPEC.md). snapshot is a pure-synchronous read of driver
state, callable from any thread. The shutdown method closes the endpoint via
an engine-hosted task, blocking on a synchronous channel until completion.
